A novel series of 7-amino 4-(2-pyridin-2-yl-5,6-dihydro-4H-pyrrolo[1,2-b] pyrazol-3-yl)-quinolines was synthesized and their TβR-1 inhibitory, p38 MAPK inhibitory, and TβR-1-dependent cellular activity were evaluated. Compound 5a was found to be a highly potent in the enzyme assay and TβR-1-dependent cellular assays. In addition, dimer (4g), with a urea linker, shows a similar enzyme and cellular activity despite a bulky substitution.
